, 7 Original application filed February 26', 1925, Serial No. 11,699 Divided and thisapplication filed and I August 25,1925.

Fig. 3 is a plan view of a'portion of the trim strip showing a stud unit secured thereto; q

Fig. 4 is a side elevation of the stud unit shown in Fig. 8.;' a

Fig. 5 is an elevati0n view of the stud unit, as viewed from the right of Fig. 4;

I Fi 6 is a section similar to Fig..2,'showin t estud unit reversed to secure the trim strip to. the body 'part.

Referring to the drawings, I have shown a trimming installation which includes the usualbody part or. frame part 1, the'upholstery fabric 2 and the wooden trim strips from pieces 0 wood and present holes or .stud parts 10, these parts may shift auto- 3 secured together by, a plurality of stud units 4, as best illustrated in F1 s. 2 and 6.

Figs. 1 through 5 illustrate t 'e first em-- bodiment of my invention and show one manner in which the parts of the installation may. be secured together by the use of the'stud units as shown in Fig. 2;

The trim stri s in this instance are formed reoessesb at the inner faces thereof for re- 13 extending from the pe ception of parts of the stud units,

as hereinafter described.

The stud units which are used to secure Serial no. 52,321.

two. stud parts are assembled, the head 7 and-neck 8 of the stud part 6 pass through the aperture 12'and areipresented beyond the base 11.- The base portion 9 seats against the base portion 11 and both stud parts are held-"in assembled relation by a plurality of ears 15 extending over the base 9 of the stud part 6. The base 9 is smaller in diameter than the diameter of the wall 13, and the aperture 12 is larger in diameter than the neck 8 of the stud part 6, thereby permitting lateral shifting of the stud parts relative to each other.

When the installation is completely assembled as shown in Fig. 2, the neck'8 of the stud part 6 is engaged with the wall surrounding the stud-receiving aperture 16 in the body part and the base 11 of-the stud part 10 seats against the upholstery 2 to hold it in place. The ringlike ortion 14 of the stud part 10 frictionally grips the wall of the recess 5 to hold the trim strip in assembled relation with the rest of the installation. The ringlike portion holds better than the head 7 'ofthe stud part 6, which passes through the aperture 16, because, of its larger area, thereby permitting the smaller stud to se arate from its aperture because that stu matically relative to the studparts 6 for alignment with the recesses when the strip is pressed over the exposed portions of the stud units.

.Referring now to Fig.6, I have shown a trimming [installation secured together by reversing t e stud units. The frame part 1 is providedwith a relatively large aperture 17 through which the rin like portion 14 of the stud part 10 passes an a plurality, of fingers 18 bent inwardly from the frame art to limit passage of the stud art 10 t rough the aperture '17. The wo entrim strip 3 is provided with a relatively small recess 19 for reception of the head 7 of the stud part 6 and a larger recess 20 is provided to receive the base 11 of theistud part 10 to permit the trim strip to fit tightly against the upholstery fabric 2.

The above described trimming installations are very simple and inexpensive, in-

asmuch as no sockets are necessary other than the stud-receiving a ertures' and recesses which can be forme in their respective parts with very little difiiculty.

The friction between the stud parts". and

'.the Walls of the recesses is sufficient to hold derstood that changes involving omission,

substitution, alteration and-even reversal of parts may be made Without departing from the scope of my invention which is best de- I secured together andfacing in opposite difined in the appended claims.

Claims; 7

1. A separable fastener unit comprising, in combination, two resilient stud members rections, one of said stud members resenting a rlnglike.socket-engaging portion and said other stud presenting a ball-shaped socket-engaging portion and means provided by said stud members to permit substantial lateral shifting of said stud members relative to each other for alignment with their cooperating stud-receiving apertures. v

2. A separable fastener stud unit comprising, in combination, a stud presenting a relativel resilient socket-enga ing portion and a relatively flat base portlon presenting a. relatively 'large aperture therethrough, a

second stud member presenting a relatively smaller resilient socket-engaging portion than'said first stud member and a laterally shiftable base portion fitting within the a erture of said first-mentioned base and a p urality of ears pressed from said first mentioned stud member and bent over said base, said smaller socket-engaging portion passing through the aperture in said base and facing in the opposite direction from said larger socket-enga 'ng portion.
